Collies led 12-0 at halftime on the back of tries two tries to hard-running back-rower Liam Cassidy and 18-0 two minutes after resumption after Sam Clune crossed. 

The Cougars ht back through tries to brothers Blair and Tye Blanchette before a try to Jacob Wood locked up the result for the home side.

With a bye next week it keeps the Dogs top two flame alight but they’ll be relying on Wests to drop at least one of their games to Thirroul or Berkeley over the final two rounds.

Thirroul drew level with Helensburgh on 12 competition points with their win over the Eagles but face a tough run home with clashes against Wests and Collegians to finish the season.

In comparison the Tigers finish their season with matches against Berkeley and Corrimal.
